My invention relates particularly to hand operated apparatus embodying abrush and suction mechanism. u

One object is tovprovidea construction which is very compact and yetreliable and convenient to' use.

Another object is to provide convenient means for removing and replacingthe brush.

In its preferred form I provide a casing containing an electrimmotor anda suction fan together with a brush driven from the shaft of the motor.The brush and motor shafts are at approximately right angles to eachother and connected by a quarter turn .5 belt. A part of the brush is eosed in a suitable manner and one wall o the casing is made removable soas to permit convenient access to the brush and to the pulleys and belt.One form of the invention is shown and claimed in my Patent 1 711,132,in which the bottom wall is removableand rovided with openings for thebrush. e e form shown and specifically claimed herein has the rear wallremovable and may also have the bottom wall removable. By thisrearrangement it becomes more convenient to assemble the brush and beltand to remove the same. This also provides a bearing surface sodisposed-*with respect to the casing and its handle as to facilitate theuse of the device on a. small and irregular surface.

Fig. 1 is a side view and partial section of one form of apparatusembodying my invention.

Fig. 2 is a rear view of the same with the cover plate removed. v p Fig.3 is a fragmentary view looking upwardly to show the suction mouth andbrush. Fig. 4 Vis a fragmentary sectional view of a handle 12 mayconveniently serve as a pasmodication. Fig. 5 is a sectional view of thesage for tlie discharge of the dirt which is loosened and sucked up bythe device.

The brush 13`may be of any suitable type having bristlessuitablyvsecured in a shaft 14 positioned in open ended bearing seats or55 bearing sockets 15 in opposite side walls of the chamber. The shaftis provided with a pulley 16 which in this form is arranged in theapproximate center of the shaft. The shaft 17 which extends from themotor is so provided with a pulley 18 which is connected to the pulley16 by a quarter turn belt 19.

Prior to my invention the belts in devices of this character have beenformed of rubber so as to be sufi'iciently elast-ic to permit thereplacement of the brush and the attachment of the belt. According to myinvention, however, this belt 19 may be made of leather or any othersuitable durable and flexible mate' rial. The bottom of the` chamber ispreferably provided With a cross bar 20 beneath the pulley 16 on thebrush shaft so as to prevent the ulley from comingin contact with the oos.

g The rear end of the chamber is open so as to allow convenient accessto the. interior thereof or'the purpose of inserting the brush and thebelt and to facilitate the removalof the same.. In this connection Iprovide a cover plate 21 which is detachably secured to 30 the chamber,preferably with tight joints so as to avoid leakage around its edges.Preferably the cover will be secured at the bottom 22 and the upper edgeat 23.

The bottom wall 24 in which the suction 85 openings 11 are located mayalsobe removable and may be formed as a part ofor im tegral with therear part 25, as shown in Fig. 5. The casing for such a constructionwould of course be open at the rear and also at the bottom, as shown inFig. 4. Such a construction provides an opening 26 at the bottom and anope ing 27 at the rear so as to even more faciliate the insertion of thebrush and the attachment of the belt. The cover is now formed of thewalls 25 and. 24 and is releasably secured to the casing`by means ofhooks '28 and 29 or other suit-able means.

I claim 1. A vacuum cleaner comprising a handle member, a casing mountedon the upper side of the handle memberand having an exten- 'sion at itslower end extending below the handle member, Said. extension having anopening at its lower end transverse to the length of the handle memberand having an opening at therear end, a motor supported in the casinwith its axis parallel to the handle mem er and havino' a pulley on oneend of the motor shaft, albrush detachably mounted in the extensioninposition for its bristles to project throu h the bottom openin aquarter turned elt`connecting the pu ley with the brush and accessiblethroughy the rear end opening of the casing extension and a cover plateclosing the reapi` end opening in the casing, said brush and belt beingcom pletely exposed 'and removable through said rear endopening when thecover is removed.

2. A vacuum cleaner comprising a casing c having a rearward and downwardextension,

a rotary brush havinga shaft detachably supsaid extension includingbottom, side and s rear walls forming a chamber, a motor mounted in thecasing, said extension having open ended bearing seats on the oppositeside walls,

ported 'n said bearing seats in said chamber adjace its bottom wall, abelt operatively conneo ing said motor'and said brush, said rear Walland said bottom wall having openings, said brush having a portionprojecting through the bottom opening, and a plate de' tachabl mountedon said extension and ada te to cover the opening in ,said rear wal YRUBIN BASS..
